Argument Builder
The Argument Builder (Research OS Stage 12) lets you sequence the claims in a project into a structured nine-step argument and warns you about weak spots before you commit to a conclusion.
What it does
You drag claims from the Claim Ledger into an ordered argument. Each step fills one of nine canonical slots that together make a complete scholarly case:
- Problem - the situation or puzzle the work addresses.
- Gap - what is missing or unresolved in current knowledge.
- Frame - the theoretical or conceptual lens applied.
- Method - how the claim is established or tested.
- Evidence - the core supported finding the case rests on.
- Analysis - what the evidence means once interpreted.
- Counterargument - the strongest objection and the response to it.
- Contribution - what this adds that did not exist before.
- Implication - why it matters: consequences and next steps.
Claims are reused, not rebuilt
The builder never duplicates your claims. It reads them live from the Claim
Ledger (the same research_assertion records, with evidence from
research_assertion_evidence). Attach a claim to a slot from the picker on each
step; the step stores only a reference, so editing the claim in the ledger
updates it everywhere.
If a project has no claims yet, add them in the Claim Ledger first, then attach them here.
Weak-spot warnings
As you build, the system runs a heuristic check (no AI required) and flags:
- Uncited step - a step whose claim has no evidence attached at all.
- Single-source over-reliance - a step whose claim has two or more citations but they all come from one source.
- Missing step - any of the nine slots not yet placed in the chain.
- Contested claim - a step using a claim marked rejected, contested, disputed or weak, which signals a contradiction to resolve.
- Conclusion stronger than the evidence - a Contribution or Implication step resting on a low-confidence, weak-status or uncited claim.
Warnings appear inline on each step and collected in the side panel. They are advisory: nothing blocks you from saving, but a clean panel means every step is cited and the chain is complete.
Using the canvas
- Central thesis - name the argument and state the single claim it exists to defend.
- Add step - choose a slot and (optionally) a claim, then add it.
- Attach / change claim - use the per-step picker to bind a claim, or pick "No claim attached" to clear it.
- Reorder - the up/down arrows move a step within the sequence.
- Remove - the trash button takes a step out of the argument (the underlying claim stays in the ledger).
- Missing steps - the side panel offers a one-click button to add any slot you have not placed yet.
There is one argument per project; it is created automatically the first time you open the builder.
